[texts]Data Assimilation and Transport Modeling in Terrestrial and Planetary Atmospheres - Houben, Howard C
Data assimilation is a blanket term used to describe a number of techniques for retrieving important physical parameters from observational data, subject to constraints imposed by prior knowledge (such as, in the case of meteorology, the primitive equations that govern atmospheric motion). Since these newly developed methods make efficient use of computational resources, they are of great importance in the interpretation of the voluminous datasets that are now produced by satellite missions...

[texts]Supernova remnants and the carbon abundance in M33 - Blair, W. P.
The IUE and optical spectral data on a supernova remnant in M33 was combined in order to determine the abundance of carbon in the interstellar gas of M33. New shock model calculations were used to guide the interpretation and a substantially lower value of the ratio c/o than was assumed previously for M33 may be necessary to explain the data. However, some inconsistencies in the observed and predicted line intensities indicate that the spectra may be partly contaminated by H II region emission o...

[texts]Creation of High Resolution Terrain Models of Barringer Meteorite Crater (Meteor Crater) Using Photogrammetry and Terrestrial Laser Scanning Methods - Brown, Richard B.
Barringer Meteorite Crater or Meteor Crater, AZ, has been a site of high interest for lunar and Mars analog crater and terrain studies since the early days of the Apollo-Saturn program. It continues to be a site of exceptional interest to lunar, Mars, and other planetary crater and impact analog studies because of its relatively young age (est. 50 thousand years) and well-preserved structure. High resolution (2 meter to 1 decimeter) digital terrain models of Meteor Crater in whole or in part wer...

[texts]Reaction propagation test. Evaluation of the behavior of nonmetallic materials in hydrogen - Smith, I. D
Results of tests conducted to evaluate the behavior of nonmetallic materials in hydrogen are described. The reaction propagation test simulates the conditions resulting from the interaction of an electrical wire in an overload condition in contract with a material in the test medium. The test is designed to evaluate the behavior of a material subjected to an energy input (usually heat) sufficient to cause a reaction which propagates to consume larger quantities of the material...

[texts]Method for alleviating thermal stress damage in laminates - Hoffman, C. A.
The method is for metallic matrix composites, such as laminated sheet or foil composites. Non-intersecting discrete discontinuities are positively introduced into the interface between the layers so as to reduce the thermal stress produced by unequal expansion of the materials making up the composite. The discontinuities are preferably produced by drilling holes in the metallic matrix layer. However, a plurality of discrete elements may be used between the layers to carry out this purpose.

[texts]Apollo 16 mission anomaly report no. 9: Lunar roving vehicle electrical system meter anomalies - NON
The off-scale low indications of the voltmeters for batteries one and two at initial powerup of the Apollo 16 lunar roving vehicle were analyzed. No single condition was found that would explain the anomalous meter indications. It is concluded that the intermittent conditions must have existed in the multiple wire splices to the meters.

[texts]Issues Related to Cleaning Complex Geometry Surfaces with ODC-Free Solvents - Bradford, Blake F.
Implementing ozone depleting chemicals (ODC)-free solvents into full-scale reusable solid rocket motor cleaning operations has presented problems due to the low vapor pressures of the solvents. Because of slow evaporation, solvent retention is a problem on porous substrates or on surfaces with irregular geometry, such as threaded boltholes, leak check ports, and nozzle backfill joints. The new solvents are being evaluated to replace 1,1,1-trichloroethane, which readily evaporates from these surf...

The problem of accurately reconstructing a piece-wise smooth, 2(pi)-periodic function f and its first few derivatives, given only a truncated Fourier series representation of f, is studied and solved. The reconstruction process is divided into two steps. In the first step, the first 2N 1 Fourier coefficients of f are used to approximate the locations and magnitudes of the discontinuities in f and its first M derivatives...

[texts]Elastic moduli of precompressed pyrophyllite used in ultrahigh pressure research - Sachse, W.
The propagation of ultrasonic pulses in pyrophyllite specimens was studied to determine the effect of specimen precompression on the measured elastic moduli. Measurements were made at room pressure and, for the precompressed specimens, to pressures of 3 kbar. Pyrophyllite was found to be elastically anisotropic, apparently the result of the fabric present in our material. The room pressure adiabatic bulk modulus as measured on specimens made of isostatically compacted powered pyrophyllite was de...
